I keep seeing this #pictogram (top right hand corner, stick man holding a #spanner and wearing a #rosette ) on parts of #VW cars (it was also on the #DSG gearbox of my Polo). I know it means "qualified/trained #mechanic only should work on this assembly and the one in my picture is a specification of oil and refrigerant for the airco),
I've not found any sources that #mechanics in Germany get #rosettes on completing their training, and in UK a rosette is either associated with political party membership or you might get one if you won some kind of #sports event (or a beauty contest) so I'm curious as to why its used..
